ELEVATOR-BIN.

\ SPECIFICATION forming part of Letters Patent No. 704,805, dated Jt y 190% Application filed August 27, 1900. Serial No. 28,254. (No model.)

To all whom it ntcty concern:

Be it known that I, JAnns ALEXANDER JAMIESON, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Elevator-Bins; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention, although hereinafter described as applied to the construction of abin for an elevator, is equally applicable in its various featureswherever columns, walls, wall-joints, or hopper-bottoms are required.

Heretofore in the construction of elevatorbins a large number of stringers and vertical timbers have of necessity been used with the attendant unequal shrinkage and compression or collapse, the shrinkage being naturally greater transversely than longitudinally of a timber and the compression or collapse of a timber subjected to end load being almost mil, while when subjected to side load it is, comparatively speaking, considerable.

The prime object of my invention is to provide a structure that will obviate these defects and at the same time be fireproof, easily constructed, and have all strains to which it may be subjected evenly distributed therethrough and finally concentrated'in supporting-columns.

The invention may he said, briefly, to consist in providing a series of columns,,a-bin, and a hopper-like bottom for said bin, all of novel construction. The columns each consists of a metallic tube vertically arranged, filled with concrete, and supported upon a suitable base, preferably consisting of a series of pedestals, each made up of a hollow conical metallic section filled with concrete and sunk in the ground.

My improved bin bottom, which in the present embodiment is suspended from the top of columns constructed on the above principle, consists of a series of metallic strips bent and arranged relatively to one another to form a hopper of truncated pyramidal form, the ends of these strips being secured at their ends to composite girders of metal and concrete, which constitute a medium through which the pyramidal hopper is hung from the columns, the interior surface of this hopper being lined with concrete. My improved bin extends above this hopper-bottom and consists of a series of corrugated plates constitutingthe walls-thereof and embedded at their endsin composite corner-columns superimposed upon the first-mentioned col-' umns, while said walls rest upon the tops of said composite girders. This construction when the bin is full causes all stresses,

whether tension, compression, or torsion, due

to the weight of itself and its contents, to be uniformly distributed throughout the supporting-columns, each columns quota being concentrated thereto. A

For full comprehension, however, of my in vention in its entirety reference must be had to the accompanying drawings, forming a part of this specification, in which like symhols indicate the same parts, and wherein- Figure 1 is a pianview of two adjoining bins, one of which is partly in section and a portion of the lining thereof partly broken away. Fig. 2 is a vertical sectional view taken on line A B, Fig. 1. Fig. 3 is an enlarged transverse. vertical sectional view of the top of one of my improved supportingcolumns, illustrating particularlyone of the capping-plates; and Fig. 4 is a plan view thereof.

These pedestals are sunk to a depth to have their open tops (Z on a level with the surface of the flooring, and an annular foot-casting 6,

formed with an annular vertical flange f, rests upon each of these pedestals. These foot-castings support the columns, each of which consists of a vertically-arranged tubular metallic casing g, of a diameter to have its lower end closely fit inside of the vertical flange f, while it is also filledlwith concrete 0 and has a top casting t' resting thereon; The function of these top castings is to provide means wherefrom the truss-plates of'a series of composite girders can he hung, as will be presently shown, and each of said castings is formed with a central opening j and a depending peripheral flange Z; to closely fit over the Each of my improved pedestals consists of i top of the casing g. The top thereof is made tral recess 11 disposed with its sides parallel to the four sheared-off sides m. The object of the central opening j is to allow a portion of the cement to for securing the casting to the top of the concrete column to project therethrough and form a binder.

The composite girders extend between the tops of each'adjaceut pair of columns and are supported at their ends by these top castings, as follows: A downwardly-bellying trussplate 0 has its end portions taking over and resting upon the sides m of the portions of the top surfaces of the top castings which intervene said sides m and the adjacent sides of the squared recesses, while the ends proper thereof are bent over said adjacent sides of and depressed into said recesses. Abrace in the form of a channel-iron 13, disposed with its flanges projecting upwardly and corresponding in width to said truss-plate, rests upon the portions thereof that lie upon the top castings and are of a length to extend from the edge of the squared opening in the top casting from which one end of the truss-plate is hang in g to the adjacent edges of the squared opening in the top casting from which the other end of the truss-plate is hung, the space between each truss-plate and the channel-iron resting thereupon being, like the columns and pedestals, filled with concrete 0, thus constituting composite girders consisting of a concave truss-plate hung from its supports, a flat brace or tread resting upon the ends of said truss-plate, and a concrete filler between said trussplate and brace. The hoppershaped bin-bottoms are suspended from these composite girders, and each consists of four series of metallic truss-strips r, the strips of each series being riveted at their lower ends to one side of a rectangular open casting 8, while theirupper ends are bent and hooked over the adjacent flange q of the channelironadjacentthereto. Theremainderofeach side is made up of a series of metallic trussstrips arranged side by side and having their ends 2 bent to form hooks to take over the before-mentioned adjacent flanges q of the inclosing channel-irons. Each of these lastmentioned strips is bent to form a horizontally-extending portion 3 and diagonally-extending portions 4. The diagonally-extending portions of the strips of two of the oppositely-disposed series are lapped over the diagonally-extending portions of the other two series, thus providing diagonal supportingsections and longitudinal trussing portions to brace said diagonal supporting portion, the

, whole being hung from the composite girders by their hooked end 2. The space between the flanges q of each channel-iron is also filled with cement. The walls of the bins, to a series of which these hoppers act as bottoms,

are made up of a number of plates 10, of steel or other strong sheet material, longitudinally corrugated and horizontally arranged and secured together by angle -plates 12. These corrugated plates are supported upon the composite girders and rest upon the concrete filling of the channel-irons thereof, while the spaces 14, inclosed by the corner-plates, are located directly above the columns. These spaces 14: and the interior of the pyramidal sides of the hopper,like the tubular casings g of the columns, are respectively filled and lined with concrete 0, the ends 15 of the wall-plates being embedded in the concrete filling of the corners, and the walls and corner-pillars thus constructed are continued until the required height of bin is attained.

The casting S is formed on the edges of its open under side with guideways 15 for a slide valve or door 16, operated by a lever 17, to control the flow of the substance from the bin. The stresses due to the load of a full bin or a series of full bins will in structures according to my invention be exerted downwardly upon the top of the corrugations in the wall-plates and laterally throughout the area of said Walls and from said walls in tension to the composite corner portions and in vertical load mainly by the said composite corner portions and partially by the composite girders, which latter in turn will transmit it to the composite columns.

Stress in torsion is obviated in each of the composite girders by the concrete filling and the distribution of its proportion of the load carried by the hoppers contiguous thereto throughout its length.

In my improved columns the casing 9 serves solely as a stay for the concrete beforeit hardens and to prevent the perimeter thereof when dried and hardened cracking otf or crumbling.

It is obvious thata series of bins constructed according to the foregoing will not be subjected to the unequal strain due to the unequal shrinkage and compression or collapse attendant upon the use of timbers in the construction of bins for elevators 'or the like. It is further obvious that my improved columns, girders, and Walls can be independently or collectively used in the construction of buildings other than elevator-bins and that my improved hopperbottom can be supplied to other uses than described and in connection with other supports than shown and the easings of the pedestals removed before they are sunk in the ground, all without departing from the spirit of my invention.
